Preheat oven to 325˚F. Line a sheet pan with foil or parchment paper for easy cleanup. Add almonds to prepared pan.
Place in oven and roast for 15-22 minutes OR until golden brown, stirring gently to redistribute every 5 minutes.
*When you use flaky sea salt in a recipe like this, rub it between your fingers as you add it, breaking up the large flakes as you sprinkle it.
If you have a Costco near you, they sell large bags of slice almonds for a very reasonable price. Trader Jo's also always has a great buy on sliced almonds.
